Rapa Nui is 3,700 kilometres from the Chilean coast and the most remote inhabited island on earth. Almost everything worth seeing is inside the Rapa Nui National Park, and since 2018 the park requires a ticket and, at several sites, a local guide.
That is not a formality: the guiding requirement exists because the island decided how its own heritage would be visited. The operators below are Rapa Nui-owned.
